Comminution provider Pilot Crushtec’s Namibian dealer, Rex Quip, has supplied services to Africa-focused uranium-miner Paladin Resources’ Langer Heinrich uranium plant.
The Langer Heinrich mine, situated 85 km from Swakopmund, in Namibia, needed to process high-grade recyclable material previously stockpiled as it could not be effectively sized by the existing attritioner plant. Rex Quip produced –2-mm material from ore that ranged in size from –75 mm to 10 mm.
Pilot Crushtec manager for Rex Quip in Namibia Wayne Warren comments that the company was able to assist with quick delivery. “What clinched the deal was that the company has the equipment the mine needed readily available, so it was just a matter of weeks before the plant was dispatched to site,” he adds.
“The plant was delivered in three weeks. Since then, it has been working satisfactorily,” confirms Langer Heinrich Uranium senior metallurgist Lionel Coetzee.
At a purchase price of R3-mil-lion, Pilot Crushtec supplied a complete modular crushing plant, mounted on skids for easy relocation. The modular crushing plant includes a grizzly feed hopper, a modular jaw crusher, a vertical shaft impact crusher, a screen, and six 600-mm-wide conveyors with slewing capabilities.
Pilot Crushtec sales director Graham Kleinhans says that the client had very specific needs, which the company has met and the client is turning a previously difficult-to-size product into a valuable resource. He concludes that the quality of material being produced and production capa- city have exceeded the company’s expectations and that there is a positive outcome for all concerned.
Rex Quip set up an office in Swakopmund in 2008 to ser- vice a number of uranium mines being expanded in the area; so the company is locally situated to provide the best support to these mines.
Coetzee adds that several ‘tweaks’ are currently being imple- mented in an attempt to increase the efficiency of the plant. In addition, a wet-screen pro-cess may be introduced to further increase production and to assist in conveying the crushed product to the main processing plant.
